Sound moves outwardly as a wave, in all directions, from its original source. These waves travel as vibrating pressure undulations interacting with everything in their path. Depending on the nature of the impedance it encounters, a sound wave can be deflected, reflected or even absorbed. In essence, this is what acoustic treatment is; undertaking procedures using specific materials or electrical devices to minimize unwanted or unnecessary sounds.
The need for acoustically treating a particular area or room can depend on lifestyle, legal issues or environmental factors ranging from a operating a home theater system, to owning a recording studio or even residing close to a major city highway or airport.
With this in mind, it is easy to understand why acoustically insulating a specific region could be desirable. It can minimize the amount of noise pollution entering from an external source, or conversely keep sound contained within a particular area.
Home theaters are an excellent example of this; Bad acoustics will render the surround sound effect of your favorite movies completely lacking in their majesty because the sound will 'leak' out of the room like water through a sieve. Insulating the room not only 'traps' the sound within the confined space, causing the audio reverberate and 'surround' you, but also prevents any external noise entering the room and ruining the ambiance of the movie.
There are a variety of materials available which adequately perform the task of acoustic insulator. Some are of course better than others, but there is often a compromise between budget, weight constraints, size constraints and time restrictions. Porous foams and viscoelastic polymers are excellent insulators because they 'deform' under the wave's vibrations, absorbing the mechanical energy and converting it to heat, dissipating said heat within the immediate environment. Denser materials like concrete, brick or steel absorb some of the sound, but due to their density will reflect most of it.
